IMPROVEMENT IN MACHINERY FOR MAKING ROPE.

Specification forming part of Letters Patent No. 14,194, dated February 5, 1856.

To all whom it may concern:

Be it known that we, OLIVER S. HAZARD and ISAAC PECK, both of Coventry, in the county of Kent and State'of Rhode Island, have invented a new and useful Improvement in Machines for Making Ropes; and we hereby declare the following to be a true and exact description thereof, reference being had To the drawings herewith presented, said drawings constituting a part of the said description. (See the drawings.)

Figure 1 is an elevation or front View of the frame A with its Spindle B supporting a disk of metal D, on which are seen two of the fliers F F, which are turned by the common device of wheels S S and pinions P I), placed at the lower end of the flier-shafts .I J, which project below the disk D and receive their rotary motion by the wheels S S revolving round (and in contact with) the stationary wheel IV. (Seen more conspicuously at Fig. 2, which is a top view of the flier-gear.) The tops of the fliers are connected with the oblique tubular shafts g g. These are supported in sockets made in the collar or beveled plate E, which is fastened on the spindle B and revolves with it. The upper ends of the tubular shafts g g have also small disks of metal H H, on which are supported the feeding-rollers R R, Fig. 6, and on the shaft of one of each pair of the feeding-rollers is a worm-wheel T, which is turned by the endless screw u. This screw u is supported on a small shaft V, which shaft is fitted loosely in the disk H, and projecting below the disk is furnished with a wheel X, which is turned on its own axis by revolving This wheel Y is fastened to the plate E. (See Fig. 3, which is a reverse view of the gig-disk H, showing the'gear of the worm-shaft V.)

Fig. 4 is the trumpet-guide Z, being loosely fitted into the shaft g and extending through its whole length. It will be seen that the upper end of the flier F is connected to the oblique shaft g by the universal jointC.

In Fig. 1,II represent the floor of the building, and the spindle B, extending below the floor, may be put in motion by power communicated to its lowerend. This carries the disk D and its Iiiers with its wheels I), which, revolving round the stationary wheels XV, turns the flier on its own axis, and the flier, being coupled by universal joint to the tubulaishaft g, turns itand its disk II, carrying its feeding-rollers R R, and these rolls measure out the strands in exact proportion for the twisting and laying of the cord.

In making ropes from carded sliver of cotton or other fiber a difficulty always occurs in piecing up the strands from time to time as the cans are exhausted or whenever the sliver happens to break, for before any such occurrence can be seen by the attendant the end will have passed up above the rollers, and when the break or deficiency is discovered it must be spliced above the rolls, and then the strand being loose must be tightened by being drawn down or let down to bring the strands even. Now the sliver has no strength below the rolls and cannot kbe drawn back through the guide. IVe have therefore provided a movable self adjusting trumpetshaped guide Z, which compresses the sliver and. is suspended on the sliver, extending up through the tubular shaft close to the rollers, and when the strand is to be tightened We allow the trumpet to drop back by opening the rolls, and when the machine is again put in motion the rollers draw the trumpet again up to its place.

Ve have found this to bea very important device, as it affords the means of adjusting the most delicate strand with facility and perfect safety by merely opening the rolls.

That We claim as our invention, and desire to secure by Letters Patent, is-

The movable self-adjusting trumpet-guide Z, as above described.

In testimony whereof we hereto subscribe our names in presence of two witnesses.
